Comments on "Effects of wall roughness on flow in nanochannels"
arXiv:0909.0554
Abstract
We make remarks on Sofos {\it et al.}'s [{\it Phys. Rev. E} 79, 026305 (2009)] paper. The focus is about the monotonicity of the slip length of which it is different from previous similar numerical simulation. We also offer a possible explanation for this.
